  plot(x, y, 'o', markersize=10) # big
  plot(x, y, 'o', markersize=20) # bigger

All legal html color names are supported

>>> plot(x, y, 'o', markersize=10, markerfacecolor='green', markeredgecolor='red') 

Eg

    lightblue            : #ADD8E6 	
    lightcoral           : #F08080 	
    lightcyan            : #E0FFFF 	
    lightgoldenrodyellow : #FAFAD2 	
    lightgreen           : #90EE90 	
    lightgrey            : #D3D3D3  	
    lightpink            : #FFB6C1 	
    lightsalmon          : #FFA07A 	
    lightseagreen        : #20B2AA 	
    lightskyblue         : #87CEFA 	
    lightslategray       : #778899  	
    lightsteelblue       : #B0C4DE 	
    lightyellow          : #FFFFE0 	


# or use aliases for less typing
>>> plot(x, y, 'o', ms=10, mfc='green', mec='red') 

# or rgba or hex
>>> plot(x, y, 'o', ms=10, mfc='#008000, mec=(1,0,0,1) )


    Colombes> Or perhaps is there some other Python MatPlotLib or
    Colombes> other Python module functions that allow variable size

The scatter command supports markers with varying sizes and colors.
